I wear helmet size large and this fits good
The only option was size XL but after PULLING it on tight, it feels like it wants to pop off the top of my head until I pull my helmet on. And it does not cover my earlobes like the picture shows. I'm not an ogre of a guy, only 5'9" so my head isn't all that big. Otherwise the material seems robust and the contoured shape makes for clean fit, no ripples or bunched up material, it's just small for and "XL."
Very nice skull hat ..
I had othe helmet liners but they didn't breath so they were very hot. This product has ventilated material so it's very comfortable in warm weather.
